Insinuative metadata

If information really wants to be miscellaneous, as David Weinberger would have it, this is good news for those thirsting for the sort of data that rarely rises to the level of speech because it has no commercial value to a vendor corporation or to a metadata corporation such as an ad agency.

Regardless of its value to the public.

Some sites that offer to waltz repressed or inexplicit data into official/corporate datastreams:

Oil Standard

Oil Standard is a web browser plug-in that converts all prices from U.S. Dollars into the equivalent value in barrels of crude oil. (Mike Mandiberg)

Delocator

Enter a zip code to locate a noncorporate cafe, book store, or movie theater near you. (xtine hansen)

Personal Kyoto

Track your residential or commercial electric usage - if you're in NYC. (Ben Engebreth)

The Real Costs

Firefox plug-in that inserts emissions data into travel related e-commerce websites. The first version adds CO2 emissions information to airfare websites such as Orbitz.com, United.com, Delta.com, etc. Following versions will work with car directions, car rental, and shipping websites. Think of it like the nutritional information labeling on the back of food... except for emissions. (Mike Mandiberg)

(All the above cribbed from an IDC post by Mandiberg).
